High purity: ≥99.95% tungsten for high-temp resistance and low thermal expansion.
Precision customization: OD 6–200 mm, ID 3–180 mm, length ≤1500 mm; small-batch sampling.
Process control & QA: powder metallurgy with chemical/mechanical/surface checks; low impurities (single ≤0.01%, total ≤0.05%).
Thermocouple protection: shields sensors in extreme heat.
Sapphire furnaces: structural components for crystal growth.
High-temp sintering: furnace elements sustaining thermal stress.
Chemical composition (purity/impurity control)
Mechanical properties (strength, hardness)
Surface inspection (smoothness, defect-free)
Send your specifications (grade, size, quantity) — quotation and lead time within 12 hours. Trial orders with flexible MOQ are supported for evaluation and qualification. All materials are supplied with EN 10204 3.1 MTC and full inspection documentation for export compliance.
LuminaTitanium provides high-purity (≥99.95%) tungsten tubes produced via powder metallurgy. With excellent high-temperature strength and low thermal expansion, our tubes are configured to exact OD/ID/length for thermocouple protection, sapphire furnaces, and high-temp industrial equipment.
